Integral Orifice DP Flow Meter Run Assembly

The integral orifice meter run assembly is a differential pressure flow meter for the municipal water and wastewater industry. They’re specifically designed for smaller line sizes where the surface roughness, weld seams, and other geometrical imperfections have a relatively big influence on the flow measurement uncertainty. This DP flow meter, from KROHNE, features a minimum length of upstream and downstream pipe. Thus, it reduces additional uncertainties of the installation to a minimum.

This DP flow meter is suitable for process and allocation measurement of gases and liquids such as viscous fluids, fluids with suspended solids, or fluids with gas entrainment. We offer the complete orifice assembly with orifice meter run, DP transmitter, valves, accessories, engineering, and documentation. This DP flow meter comes pressure tested and ready for commissioning.

The meter run is available in various designs and is compliant with the requirements of the ISO 5167, such as pressure tap orientation and dimensions. It is fully machined and straightened to meet the highest dimensional expectations. If necessary, we can provide an additional calibration in line with the final operating conditions. We also supply special constructions such as redundant taps, integrated flow conditioner, certain paint specifications, or advanced NDTs from one source and in accordance with relevant standards (ISO 5167, etc.).

OPTIBAR DP Flow Meter

The sophisticated OPTIBAR DP 7060 and the compact OPTIBAR DP 3050 DP transmitters are the perfect companion for this DP flow meter solution. They are 3D linearized and ensure advanced performance even at high static pressures. Furthermore, the OPTIBAR DP series has outstanding long-term stability and a low total cost of ownership with a reduced need for field calibrations.
